Two former Parramatta Eels players are accused of harbouring semi-automatic weapons and possessing more than half-a-million dollars in cash after dramatic arrests in Sydney's Centennial Park yesterday.

"The family have to try and pick up the pieces of this awful, awful tragedy."

Ms Parkinson recommended that criminal sanctions apply to breeders of restricted breed dogs and that the onus of establishing whether a dog is classified as such rest on the owner rather than on authorities.

The coroner also recommended mandatory reporting by veterinarians of any restricted breed or suspected restricted breed dog which is unregistered, not desexed and not microchipped as required by law.

Mr Nwokolo said the family believes the measures will go a long way to ensuring what happened to Ayen will not happen to other people.

"I would encourage and ask on behalf of the family that the government put in place the recommendations," he said.

Ms Parkinson found Lazor Josevski and Nick Josevski disobeyed the law by failing to secure their dog and prevent its escape from their property as required under restricted breed dog laws.

They also contributed to her death by trying to hide a restricted breed dog from authorities.

Ms Parkinson also found Zlate Lazarovski, who supplied the dog to his cousin Nick Josevski, also contributed to Ayen's death because he knew the dog breed was restricted and his breeding of it was unauthorised.

The Australian Veterinary Association did not support mandatory reporting of restricted breeds by veterinarians, saying it is not possible to definitively identify a pit bull terrier.

The association said the recommendations could discourage owners from seeking care for their animals, leading them to suffer needlessly.
